I believe it would add depth to the experience instead, just like being actually next to the person, the crew has new ways to verify intention, the impostor has new ways to lie and enter the safe zone of all the rest, a whole range of possibilities could open, hearing conversations through walls, being able to hear the people near you even if in the dark, a talk with the impostor before being killed, etc.
What if you could hear murder?
That's the idea.
